#6246: SAGE_FAT_BINARY still doesn't work

----------------------+-----------------------------------------------------
I built a Sage-4.0.1 on sage.math (a 32-bit vmware machine actually) using
the SAGE_FAT_BINARY environment variable. This set MPIR's --enable-fat
option (or should have!). I then dropped the binary on cicero (on
skynet), and it does *NOT* work at all. The problem is definitely still
MPIR. This will have to get fixed soon.
At least this nails down that MPIR is the problem, and gives me a
straightforward testcase.

I then rebuilt MPIR with "sage -f mpir-1.2.p2" and Sage starts up. But
then it *does* die on use of ATLAS:

So I think all the "SAGE_FAT_BINARY" stuff -- the atlas only using sse2,
the MPIR building FAT -- absolutely none of it works at all.
But again, now that there is a good test system in place (build on
sage.math, test on cicero), this will be fixable.
